No job is more stressful, dangerous or exhilarating than those of the Firefighters, Rescue Squad and Paramedics of Chicago Firehouse 51. These are the courageous men and women who forge headfirst into danger when everyone else is running the other way. But the enormous responsibilities of the job also take a personal toll. With big reputations and hefty egos, the pressure to perform and make split-second decisions is bound to put squad members at odds. When a tragedy claims one of their own, there's plenty of guilt and blame to go around. When it's "go-time" though, they put their differences aside and everything on the line for each other. From renowned Emmy-winning producer Dick Wolf.
Chief Pridgen (guest star Matthew Del Negro) comes under fire after making a tactical error during an apartment fire for which he throws Lt. Casey (Jessie Spencer) under the bus, leading Lt. Severide (Taylor Kinney) to take it upon himself to clear the problem. In an effort to further cover himself from any wrongdoing, Pridgen enlists the help of Lt. Welch (guest star Kenny Johnson), who is faced with the choice of whether to fit in with the firehouse or follow his superiors self-serving orders. Elsewhere, Mouch (Christian Stolte) is floored upon learning that his donation to a fertility clinic has resulted in a child who, now a young adult, wants to meet him. Meanwhile, Brett (Kara Killmer) and a reluctant Cruz (Joe Minoso) take Dawson (Monica Raymund) out on a double date and Boden (Eamonn Walker) focuses his efforts on his duties at home as a father.
